I think we are just arguing semantics here.
According to your view, the difference between an evil person, and an insane person is the way they arrived at that altered perception. an insane person arrived at that via ailment distorting his view of the world, while an evil person arrived at that perception through real world experience and logic, how ever twisted.
In your opinion, is a crazy person, one that has a messed up perception of the world caused by ailment or outside influence?
The line between insane and evil, and crazy is a blurry one.
I don’t see as big of a difference between them. They have a world view that falls outside of what we consider “normal”. No mater how they got there, the effects are the same.
Preventing it from happening, requires you to determine if it is a physical or societal ailment, and act appropriately. If it is a physical ailment, try to find out what that ailment is and treat it. if it is caused by his environment (society) then try to change it to prevent it from happening again.
Kudos for your civility. I am sometimes loathe to comment on FR for fear of the nasty backlash when I disagree with someone.
Agreed, we need to focus on preventing the kind of attack that happened in Aurora, whatever the genesis.
As for me, whenever I see a person exhibiting either insanity or evil, I plan to act immediately. I have seen the consequences of people who fear to take action.
